Continuous split course irradiation for stage I and II Hodgkin's disease: 20 year experience at the Medical College of Wisconsin.

Abstract

Between January 1970 and December 1989, 153 consecutive patients with stage I or II Hodgkin's disease were treated at the Medical College of Wisconsin Affiliated Hospitals. Eighty-eight patients were clinically staged and 65 patients underwent staging laparotomy. Ninety-nine patients were treated using continuous split course irradiation (CSCI) technique. Overall survival (OS) at 5, 10, and 15 years was 89%, 79%, and 68%, respectively. Disease-free survival (DFS) at 5, 10, and 15 years was 75%, 72%, and 68%, respectively. No significant differences were found in OS or DFS when comparing pathologically and clinically staged patients or when comparing patients treated using CSCI with those treated with the standard technique. Patients treated using CSCI tended to complete therapy in a shorter time, without increased morbidity.
